A madras (emphasis on the second syllable, similar to morass) is an Islamic school. They exist all over the arab world, and many of them teach virulent anti-semitism from pre-school on. It's been covered by 60 minutes et al.

I do think that a department of Peace would have to look at the teaching of racism, systematically and institutionally, wherever it appears. Undo this: "you've got to be taught to fear and hate / people whose skin is a different shade / you've got to be carefully taught.."

Two other things that would dramatically forward peace around the world:
(1) eliminate child-beating and wife-beating. (How? Well, that's the job of the department of Peace! But it would take a massive outreach and education program, to start with.)
(2) Educate all girls and women, at least through high school to start with.
Hatred and violence don't just pop up in graduate schools. They are planted much earlier.
